A paraboloid is a 3d surface, like a tall bowl or saddle. It is defined by two equations where one variable isn't squared and the other two are. Paraboloids come in two main types: the elliptic paraboloid (bowl-shaped) and the hyperbolic paraboloid (which looks like a delicious pringle :P).
🚨 major boring alert! 🚨
The standard equation for an elliptical (bowl) paraboloid is:
The standard equation for a hyperbolic (pringle) paraboloid is:
